Select the statements that accurately describe endocytosis.
a. The cell forms proteins that move substances into the cell against a concentration gradient.
b. The cell selectively filters small nutrients through specialized membrane pores.
c. The cell membrane pinches off to form an extracellular vesicle joined to the cell by filaments.
d. The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it.
e. The cell expends energy to transport materials into the cytosol.
Answer:
The correct answer is:
The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it. (d.)
Explanation:
Endocytosis is a type of active transport, where particles such as (large molecules, parts of cells, and even whole cells) are moved into cells.
The various types of endocytosis has a common feature of:
1. invagination of plasma membrane forming pockets around the target particle.
2. the pocket pinches off from original plasma membrane
3. forming a new intracellular vesicle containing the target particle.
The different types of endocytosis includes
a. pinocytosis (cell drinking): takes in extracellular fluids
b. phagocytosis (cell eating): large solid particles are taken in by cells
c. receptor-mediated endocytosis: here, receptor proteins on the cells surface, binds to complementary proteins on the surface of the target particles before endocytosis occurs.
What is the water cycle?
A: the storing of water under on or above the earth’s surface
B: the removal of water under on or above the earth’s surface
C: the continuous movement of water under on or above the earth’s surface
D: the creating of water under on or above the earths surface
C. The continuous movement of water under, on, or above the earths surface.
Answer:
C
Explanation:
The water cycle is a cycle, meaning it happens over and over again. Water isn't stored, created, or removed, it is moved around and it goes through different processes. For example, some stages of the water cycle are evaporation, condensation, precipitation, infiltration and run off.
Therefore choice C: the continuous movement of water under on or above the earth’s surface, is correct.

DPIP was used in the photosynthesis lab to measure the
-Light dependent reactions
-Production of O2
-Light Independent reaction (a.k.a. Calvin cycle)
-Production of CO2
Answer:
Light dependent reactions
Explanation:
DPIP stands for Dichlorophenolindophenol. It is a chemical compound that is used as a redox dye.
DCPIP is blue when it is oxidized DCPIP is colorless when it is reduced.
DCPIP measures the rate of photosynthesis. The redox dye is decolorized by chemical reduction when it is exposed to light in the process of photosynthesis.
DPIP was used in the photosynthesis lab to measure the light dependent reactions.
in 1994, naturalists in Australia discovered a new genus and species of conifer, Wollemia nobilis, growing in a remote area not far from the city of Sydney. This was the first new conifer discovered since 1948. Wollemi pine (not really a pine) is in a family that had global distribution in the Crustaceous period. Scientists used a variety of different evidence to decide where this rare tree should be placed in the "Tree of Life." What evidence would be necessary to determine that this is in the phylum Coniferophyta?
Answer:
The following should be the characteristics exhibited by the plant to place it under the phylum Coniferophyta:
1. Only the male cones should possess the tendency to generate pollens.
2. The plant should have the stems, leaves, and roots in the form of vegetative organs.
3. Possess the tendency to generate pinecones.
4. The plant should possess leaves in the form of a needle that stays green throughout the annum.
5. The leaves of the plants should possess cuticle deposition.

Which feature contains genetic material and is present in a eukaryotic cell but not in a prokaryotic cell?
Which two features are present in a plant cell but not in an animal cell? ************someone HELP PLEASE***********
Answer:
A DNA is contained in the NUCLEUS of a eukaryotic cell not a prokaryotic cell. Your awnser is " nucleus"
Explanation:
The feature that contains genetic material and is present in a eukaryotic cell but not in a prokaryotic cell is the nucleus. The two features that are present in a plant cell but not in an animal cell are the cell wall and chloroplasts.
1. Eukaryotic cells have a membrane-bound organelle called the nucleus that contains the DNA of the cell. It is in charge of conserving and safeguarding the genetic material, including the chromosomes that contain the genes that govern the properties and operations of the cell.
On the other hand, prokaryotic cells are devoid of a genuine nucleus. The cytoplasm of these cells contains their genetic material, which is normally one circular DNA molecule.
2. Cell Wall: The cell membrane of plant cells is enclosed by a strong cell wall. The plant cell is protected and supported structurally by the cell wall. Together with other polysaccharides, proteins, and cellulose, a complex carbohydrate, it essentially consists of these elements. Animal cells lack a cell wall and are supported instead by extracellular matrix and other structural elements.
Chloroplasts: The chloroplasts found in plant cells are in charge of photosynthesis. Specialized organelles called chloroplasts house the pigment chlorophyll as well as other pigments that are used to absorb light energy.
They do this by converting light energy into chemical energy, releasing oxygen as a byproduct and creating glucose. As animal cells lack chloroplasts, they are unable to perform photosynthesis.

Identify the remaining processes and components of the carbon cycle. organisms release CO2 atmospheric CO2 plants use CO2 combustion fossil fuels form
Answer:
Carbon dioxide (CO2) is an important component in atmosphere and Carbon cycles allows movement of carbon dioxide from the atmosphere into living things and from living things to atmosphere again.
There are four main processes included in carbon cycle that is photosynthesis, decomposition, respiration and combustion.
In respiration, living organism such as animals and humans intake oxygen and releases CO2 in atmosphere.
In the process of photosynthesis, plants take CO2 from atmosphere and convert it into oxygen (O2) in the presence of sunlight and water.
In Decompoition, the bacteria present in soil decomposes dead matter by breaking down into simpler organic or inorganic matter such as water, carbon dioxide, and mineral salt. The nutrient cycle then recycle the carbon dioxide and send back to teh atmosphere.
In combustion, the burning of fossil fuel in cars and industries releases carbon dioxide back into the atmosphere.
So, the components of carbon cycel include atmosphere, terrestial biosphere, ocean ( dissolved inorganic carbon), and sediments ( fossil fuels).

Given the following evidence; which does not support the theory of Continental Drift? A) climate
B) fossils of plants and animals
C) magnetic strips in the ocean floor
D) land features match up (like mountains) on different continents
The theory of Continental Drift does not shows evidence about climate. Thus option A is correct.
What is continental drift?Continental drift is defined as the idea that the positions of Earth's continents have changed over geologic time, giving the impression that they have "drifted" across the ocean floor.
It can also be defined as the continents moving horizontally at a huge scale in relation to one another and the ocean basins throughout the course of one or more geologic epochs.
The theory of plate tectonics, which integrates this idea, had this idea as a key antecedent.
The fit of the continents, the distribution of prehistoric fossils, rocks, and mountain ranges, as well as the placements of prehistoric climatic zones, were all used as evidence for continental drift.
Thus, the theory of Continental Drift does not shows evidence about climate. Thus option A is correct.

The surface of the villi in the small intestine is covered by a single layer of epithelial cells called enterocytes. Enterocytes absorb nutrients from the intestinal lumen as they move up the side of the villus. The enterocytes are shed from the end of the villus through apoptosis after 3 to 4 days. Consequently, new cells must be continuously supplied from the crypt and move up the villus. When a stem cell in the crypt divides, what are its immediate daughter cells
Answer:
either a stem cell or a specialized cell, such as an enterocyte
What is the main cause of an aurora?Arrange the inner layers of the Sun in order starting with the innermost layer.
Answer:
i.Core:The center of the Sun where all the Sun's energy is produced.
ii.Radiative Zone:Tiles Energy produced by nuclear reactions in the core travels to this zone through radiation.
iii.Convection Zone:In this zone, hotter gases from the base travel to the top and cooler gases sink to the bottom due to the temperature difference.
iv.Photosphere:This zone is visible from Earth. Sequence
When charged particles from the sun strike atoms in Earth's atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights. ~Earthsky

A large population of fish live in a lake. The color of their scales is determined by two different alleles of the autosomal S gene, S1 and S2. Homozygous S1S1 fish have yellow scales, S2S2 homozygotes have blue scales, and S1S2 heterozygotes are green. Scientists caught 100 fish at random and recorded their color. Among those 100 fish were 30 yellow, 50 blue, and 20 green ones. After the original sample was analyzed, an asteroid landed in the lake and killed all the fish that happened to be in one particular location. When 100 fish were sampled again, 15 were yellow, 75 were blue, and 10 were green. Was the fish population in Hardy-Weinberg equilibirim (HWE) before the asteroid hit? In an ideal population, how many generations would it take to establish HWE after the asteroid hit?
Answer:
Yes it was
two generations
Explanation:
H0: population is in Hardy-Weinberg equilibrium
Ha: population is not in Hardy-Weinberg equilibrium
P(S1) = (2×obs(S1S1) + obs(S1S2))/(2×fish(S1S1)+2×fish(S1S2) +2×fish(S2S2) )
P(S1)= (60+50)/(60+100+40)
P(S1)=0.55
P(S2)= 1-P(S1)
P(S2)= 0.45
Exp(S1S1)= 0.55×0.55×100=30.25
Exp(S1S2)= 2×0.45×0.55×100=49.5
Exp(S2S2)= 0.45×0.45×100=20.25
x²=∑ (Observed-Expected)²/ Expected
= (30-30.25)²/30.25 + (50-49.5)²/49.5+ (20-20.25)²/20.25
= 0.010203
The value at 5% significance level and degree of freedom 1 from table is 3.84. Since x² value is less than value we accept null hypothesis
It takes two generations to achieve Hardy-Weinberg equilibrium if conditions of Hardy-Weinberg are met.
Which of the following statements regarding selenium/selenoproteins is incorrect?
a. They are proven protection against colon cancer.
b. The amount of selenium in foods depends upon the soil where the plants were grown and animals grazed.
c. Selenium functions as an antioxidant.
d. Selenium plays an important role in the regulation of thyroid hormones.
Answer:
The correct answer is: A. They are proven protection against colon cancer.
Explanation:
Selenium is a mineral that can be incorporated into our bodies in small amounts when we consume certain foods, such as whole grain and dairy products. The amount of selenium in these products depends on the soil where the plants and animals were.
Selenium plays an important role as an antioxidant, which can lower the risk of developing several types of cancer. However, this doesn't mean that its consumption can prevent colon cancer, and the studies that had been done to prove its effectivity in these regards have been inconclusive.
Besides functioning as an antioxidant, selenium also is very important for the regulation of the thyroid hormones, which play an important part in metabolism.
The protein that contains selenocysteine amino acid remnants is called selenoproteins. They are found in the endoplasmic reticulum of the cells.
The incorrect statement is:
Option a. They are proven protection against colon cancer.
The statement can be explained as:
Selenium is a mineral that gets incorporated into our body through foods, dairy and whole grains. The amount of selenium depends on its amount and presence in the soil.Selenoproteins are good antioxidants that can lower the risks of cancers. But its consumption does not provide complete protection against cancers.It also regulates the thyroid hormone and plays a vital role in the regulation of metabolism.Thus, they have not proven medication for colon cancer.
